Air Rotary Screw Drive Compressor Variable Speed Screw Compressor PM Motor

Product Specification

Air Rotary Screw Drive Compressor Variable Speed PM Motor For Sale Low Noise

Air is compressible, and the volume of the air is reduced by the mechanical movement of the air compressor, and the air after the pressure is increased is called compressed air.

It is an important power source, and it has the remarkable characteristics of no pollution, clear and transparent, convenient transportation, harmless, low flammability, and not afraid of loading.

As an important form of energy generation, air compressors are widely used in all aspects of life and production. Especially twin-screw air compressors are widely used in many industrial fields such as machinery, metallurgy, electronic power, medicine, packaging, chemical industry, food, mining, textiles, transportation, etc., becoming the mainstream product of compressed air. 

LTC Compressor is exactly the professional manufacturer of screw air compressor with over 26 years experience with our own R&D, production, sales and service. High-level quality control and years of exporting experience help us win trust and loyalty of our customers around the world. Besides, OEM service is also accepted.

Machine Details&Features:

1.Intelligent control system: Omni-directional seven-fold protection, under-voltage protection, short-phase protection, reverse-phase protection, over-current protection, temperature protection, overload protection, high-voltage protection and triple early warning settings, real-time control unit safe and efficient operation.

2.High-efficiency screw air end: Screw air end is the heart pad of air compressor, which directly determines the efficiency and service life of the machine. LTC compressor adopts internationally recognized advanced SAP rotor profile, forged steel and German rotor heat treatment processing technology, which has good tensile strength, yield strength, impact toughness and fatigue resistance and other nodular cast iron screw rotors. In comparison the efficiency difference is 15%. which is more obvious after one year of use.

3.Standard large rotor ratio, low speed drive: LTC Compressor each air compressor screw air end is carefully selected, using standard screw main engine or a higher grade main engine production ratio, all using 1:1 flexible plum blossom gears in direct connection, to eliminate the phenomenon of high speed small horse cart.

4.Unique heat dissipation and cooling system: Advanced guiding design, harmonica tracer heat and cold exchange make the cooing area increase effectively, run more quickly and smoothly, take away the heat of the machine in time. The heat transfer effect of the same area is 30% higher than that of the traditional cooler. Even in the high temperature and humidity Asia-Pacific region the normal operation of the unit can be ensured.

Advantages of permanent magnet variable frequency air compressor:

1. Adopt high-efficiency permanent magnet motor, which is more power-saving and efficient than ordinary screw air compressor motor;

2. Adopt the latest generation of integrated direct connection structure, which is more stable and energy efficient;

3. Only frequency conversion technology, permanent magnet frequency conversion air compressor can save energy by up to 42% compared with ordinary screw air compressor;

4. Soft start characteristics, increase current balance, avoid current impact on the motor;

5. Eliminate the inefficient conversion process of ordinary screw air compressors from full load to unloading, saving energy by 10%-20%.

Disadvantages of permanent magnet variable frequency air compressor:

1. The temperature of the motor is too hig

2. Risk of demagnetization

3. High failure rate
